Asbestos is the common name for a group of naturally occurring mineral fibers which are known for their high tensile strength and thermal insulating properties. It is commonly found in heating system insulation, vinyl floor tiles and sheet flooring, roofing paper and shingles, cement siding shingles, and a variety of other building construction products. When asbestos is disturbed, it can break down into microscopic fibers that may become airborne. Once airborne, these fibers can be inhaled and trapped in the lungs, posing a health threat. Breathing asbestos can cause respiratory diseases including asbestosis, lung cancer, and mesothelioma, a cancer of the chest cavity lining.
